N-TAAPs from natural classical scrapie samples. Graphs show calculated concentrations (±SD) of N-TAAP peptides determined by chip-HPLC SRM mass spectrometry of digest preparations from the brain stem of individual animals, obtained by processing 2 × 1.75 ml of 10% homogenate with PK treatment. (A) ARQ/ARQ Swaledale, neutered male, homebred; (B) VRQ/VRQ Swaledale, female, homebred; (C) ARH/VRQ Texel, female, purchased into flock from farm A; (D) ARQ/VRQ white-faced Dartmoor, female, homebred (E,F) ARQ/ARQ Vendeen, female, purchased into flock from farm B. Asterisks are used to point out the peptides with pyroglutamyl N-termini.
